Yes - Your worksheet line 5 should be 0 and line 6 should be $6,000 (They are reversed). You somewhere entered in Turbo Tax you took a 6k distribution from your IRA - you did not do this, you only made a contribution, so it's getting calculated incorrectly.
Try this link which walks through how to report the Turbo Tax backdoor Roth step by step. Id say you need to re-do these steps.

Now, assuming you made a year 2021 $6,000 Backdoor Roth conversion all within the calendar year 2021 (I.ie not a 'late' backdoor) Your lines 1,3,5,13 should all have this amount. This looks correct. However lines 16 and 17 should also be $6000 and line 18 zero (or blank)
As an aside, My understanding is the 'worksheets' are to assist with calculation purposes only - this is not even submitted with your final tax return (as least was not include in my final Turbo Tax documents) So, you need not worry what is on the calculation worksheet so much, as long as the 8606 gets populated correctly. Lines 8-12 on 8606 are also just there for calculation and do not need to be populated assuming the other lines above are correct as well.
